`vTO ALL WHOMIT MAY CONCERN: y

Be it known that I, DAVID L. FURNIER, of Rostruver, in the county of Westmoreland, and State of Pennsylvania, obtaincd'Lett'ers Parent of the United States bearing date of the 12th of March, 1867, for an improved machine for washing sand and other materials, and that; I am the original inventor of the following-described `improvements in my process, which I now desire tc haveV patented in `connection with my patent bearing date March 12, 1867; and I do hereby declare that the following is a. full and exact description thereof, reference being had to `the accompanying drawings, and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and o peration. v

I construct a cast-iron pan, A, Figure 1 in which two upright cast-iron wheels, B, Figure 3, revolve, worked by a cross and upright shaft, or horizontal and driving-shafts, lunderneath the pan. C in iig. 1 represents the hose, through which the water is forced from the pumpiinto the pan, Dthe round hole in the pan, through which the sandlandfwaterpass into the riddle E. The riddle E is worked by an eccentric from the horizontal shaft. From th riddle E the sand 'and water are passed into the elevator A A, thence carried by same into the riddle of main wash, as described in my former patent of March .12, 1867. After passing through my main wash the ysand is carried to a 'platform by means of an elevator, F, Figure 4, which elevator is attached to the front of my mainwash at the point where the square openingl is found in the bottom of the lower pan, as described in my patent o f March 12, 1867. G, in fig. 4, on the top of elevator F, is the scraper, b'y which the sand, when compacted intbe boxes, can becleaied ont. The elevator F. is driven' by the same main horizontal shaft as in my main washer.

It will be seen that my improved process consists in crushing andr mixing thelsand and water by means of two or more revolving rollers in the pan preparatory to its being carried tothe main wash; s. riddle toseparate coarse' gravel, worked by anA eccentric; a set of cast-iron elevators or boxes that receive the sand and Water, mixed'as' they come from the. riddle, and are thence thrown into my main wash; and the scraper that enters each andevery elevator or box, and removes the sand und water therefrom.

Having thus describedmy invention and improvements on my former patent, I desire to claim and secure by Letters Patenti 1. The method, as herein described, of crnshing and washing sand or rock by means of revolving wheels, operated by cross or horizontal shaftbeneath the p an.

2.l The construction of iron boxes or elevators,.that receive the sand and water mixed, in the manner as and for the purpose described. v I

3. The scraper, that enters each and .every box, in the manner and for the purpose described.
